|In one cell life begins.|
|This area should have a size of 16 x 16m in the beginning. It should be regarded as a kind of cell. It should have a healthy rich base and a climatically controlled inner life. The ground which is to be cultivated would be found at a height of 10m under the desert surface. This "new system" in rectangular form at a depth of 10m could be as follows:|
The cubic form which may eventually be changed later, is dug out. The sand which is removed can be used for other buildings. The retaining walls used are the same as those used for building underground railway systems. They protrude 1 m above the desert surface. The construction and type of materials used depends on the sideward forces of the sanddrifts in that area.
In practice a cell should look something like this:
|At the beginning of the growth period the system is covered with artificial glass (plexiglass etc). One part is covered with solar cells. Another is coloured glass related to the amount of sunlight which can be expected in that area. The roofing may be opened in segments.|
|By opening and closing the
roof cell humidity can be regulated. The exchange of air and moisture is one of
the few control mechanisms which is at our disposal. The roof is opened when
the nights are cool and during the heat of the day remains closed.
The energy needed for regulation and control is taken from the solar cell system. Following is a photocollage of a cell:
|Picture 4:||At the heart of the system one year old palms are planted every 2m. The remaining ground is covered with a fast spreading groundplants. Picture 4 shows the inside view of such a cell.|
|This picture is taken from the picturebook Sahara, from Publishers BechterMuenz 1994.|
|Moisture and temperature are controlled using the moving roofpanel (not shown here). Shrubs, bushes and different grasses are also placed between the trees and according to the strength of the sun, have a regulatory effect on the humidity and provide humus for the ground. The exact type of plant suitable can be chosen with reference to the local prevailing conditions.|
